nutrient deficiency | symptoms |
---|---|
Nitrogen (N) | leaves are pale green or yellow, smaller than normal lower leaves are affected first, but in severe cases all leaves may show deficiency symptoms stems are thin, erect, and hard plants grow slowly |
Phosporus (P) | leaves are dark green, may develop purple coloration, first on undersides and later throughout, due to abnormal production of anthocyanins death of older leaves stems are thin and may be shortened plants grow slowly, and maturity is delayed. |
Potassium (K) | older leaves mottled, with necrosis of leaf tips and margins leaves may curl and crinkle a scorch around the entire leaf may eventually occur chlorotic areas may develop throughout leaf |
